NWEA Math 2 — Questions and Answers
Question 1: A rectangle has a length of 12 cm and a width of 7 cm. What is its area?
- 19 cm²
- 38 cm²
- 84 cm² (Correct answer)
- 144 cm²
Correct answer: 84 cm²
Area of a rectangle = length × width = 12 × 7 = 84 cm².
Question 2: Which of the following is equivalent to 3/4?
- 0.25
- 0.34
- 0.75 (Correct answer)
- 0.43
Correct answer: 0.75
3 ÷ 4 = 0.75, so 3/4 = 0.75.
Question 3: If x + 9 = 21, what is the value of x?
- 8
- 10
- 12 (Correct answer)
- 30
Correct answer: 12
Subtract 9 from both sides: x = 21 − 9 = 12.
Question 4: A store sells 6 apples for $1.50. How much do 10 apples cost?
- $2.00
- $2.50 (Correct answer)
- $3.00
- $3.50
Correct answer: $2.50
Unit price = $1.50 ÷ 6 = $0.25 each; 10 × $0.25 = $2.50.
Question 5: What is the value of 5²?
- 10
- 15
- 25 (Correct answer)
- 50
Correct answer: 25
5² means 5 × 5 = 25.
Question 6: Order these fractions from least to greatest: 1/2, 2/5, 3/4.
- 1/2, 2/5, 3/4
- 2/5, 1/2, 3/4 (Correct answer)
- 3/4, 1/2, 2/5
- 2/5, 3/4, 1/2
Correct answer: 2/5, 1/2, 3/4
Converting to decimals: 2/5=0.40, 1/2=0.50, 3/4=0.75, so 2/5 < 1/2 < 3/4.
Question 7: A number is multiplied by 4 and then 6 is added. The result is 30. What is the original number?
- 4
- 6 (Correct answer)
- 9
- 12
Correct answer: 6
4n + 6 = 30 → 4n = 24 → n = 6.
